Benitoite is one of those minerals everybody wants, probably because of its uniqueness, triangular habit
and rarity as a gemstone, plus the visual appeal alone is unlike any other species. This isolated gemmy
well formed rich deep blue crystal measures 2.1 cm. Quite nice considering production has ceased, old
pieces like the one pictured here will always be desirable in the future, no damage.

Wow! Here we have several out of the ordinary features for the species, first its crystal size is a whopping
2.9 cm from tip to tip, second outside of the crossite included specimens this one is extraordinary for being
all gemmy blue, and third the cluster form is another rarity from the mine, in fact I have only seen a small
handful of examples of which many were not as attractive as the piece above. The trigonal shape of the
large benitoite gives justifiable reason to boast about what is without question a splendid and
unique piece! Undamaged, size: 3.5 x 2.9 cm.

Fine lustrous smooth dark black neptunites reaching 2 cm tall erupt from a solid bed of snow-white
natrolite. The really nice thing about this piece is that no bluish gray schist can be seen which is harder
to get than one would think, in addition to 3 dimensional neptunites standing upright from on all sides.
Very distinguished small cabinet in perfect condition.

Highly desirable and rare triply terminated benitoite on matrix! Perched up on white natrolite, this choice
crystal is 1.6 cm across. Even when production was ongoing fully formed benitoites were extremely scarce,
price spikes for this reason. Today it's a joy to see one surface, real value here.

Several marvelous gem quality blue crystals measuring up to 1 cm in length sit scattered upon white
natrolite as all seven crystals enrich the piece making it more for the money if not additional color.
This miniature is a good buy, but actually most benitoites are worth purchasing.
